T0 all whom, t may con/cern:

Be it known that I, JOSEPH GOoDnrcH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Vises, of which the following is a full, clear, and exact specification.

My invention relates to bench-vises dosigned for rapid manipulation; and it has for its primary object to provide improved and efficient means whereby the jaws may be rapidly manipulated and with great power from a floor connection or treadle accessible to the foot of the operator, thus leaving both ldiands of the operator free for the work to be one.

Another obj ect of my invention is to provide improved means whereby the handle of the screw will always seek a perpendicular position when released, so as to be out of the way of the operator.

lVith these ends in view my invention consists in certain features of novelty in the construction, combination, and arrangement of parts by which the said object and certain other objects hereinafter appearing yare attained, all as fully described with reference to the accompanying drawings, and more particularly pointed out in the claims.

In the said drawings, Figure 1 is a side elevation of my improved vise. Fig. 2 is a detail perspective view of the lower connectingbar. Fig. 3 is a plan section on the line 3 3, Fig. 1, showing a detail hereinafter described. Fig. 4 is a vertical section on the line 4 4, Fig. 1. Fig. 5 -is a plan section on the line 5 5, Fig. 1. Fig. 6 is an enlarged detail section on the line 6 6, Fig. 1. Fig. 7 is aperspective view of the segment on an enlarged scale. Fig. 8 is a detail perspective view of the cam and its operating-lever. Fig. 9 is an enlarged detail section on the line 9 9, Fig. 1. Fig. l() is a detail perspective view ofthe slotted treadle-lever, partly broken away. Fig. 10a is a detail section on line 11 11, Fig. 1.

Fig. 11 is an enlarged vertical longitudinal sectional view of the screw and handle with connected parts. Fig. 12 is a transverse sec- 13 is a transverse section on the line 13 13, Fig. 11. Fig. 14 is a side elevation of the lower portion of the device, showing a modification in the operating mechanism hereinafter described. Fig. 15 is a plan section thereof on the 1in@ i5 i5, Fig. 14. Fig. 1e is an enlarged section on the line 16 16, Fig. 14. Fig. 17 is an enlarged section on the line 17 17, Fig. 14 3 and Fig. 18 is a detail hereinafter described.

1 is the fixed jaw, and 2 the movable jaw, and these are fulorumed together by any suitable adjustable means, such as the usual screw 3, by the aid of which the jaws may also be forced together after the manner of operating the jaws of an ordinary bench-vise, the screw being threaded in one of the jaws, preferably the fixed jaw, and swiveled by means of pin 4 and groove 5 in the movable jaw.

The screw may be rotated by any suitable handle, such as a sliding bar or lever 6 of the usual form; but I prefer to employ the construction best illustrated in Figs. 11 and 12, whereby the handle or lever 6 will automatically drop to a perpendicular position independently of the screw. In accomplishing this object I provide the outer plain end 7 of the screw with a transversely-projecting pin S, which for convenience of attachment and of assembling the parts is in the form of a screw screw-threaded in a transverse passage 9 in the end 7, and over this plain end 7 is placed a hub or socket 10, which isformed on or secured to the keeper 11 through which the handle or lever 6 slides. This hub is provided with an aperture 12, through which the screw-stud 8 may be introduced, and in line with this aperture is formed an internal groove 13, extending approximately half-way round, (see Fig. 12,) so that the hub will always be capable of a quarter-rotation no matter what the position of the stud 8 might be, the Groove 13 during such rotation passing over the projecting end of the stud. The ungrooved part of the hub S, however, forms two shoulders or lugs 14 15 at the extremities of the groove, and each of these is adapted to engage the stud when the hub is rotated a half-turn. Thus in the position shown in Fig. 12 where the handle is vertical, the screw 3 will be turned toward the right, if the hub 10 be rotated in that direction, but if the hub be turned to the left it will rotate a half-turn without moving the screw, but will begin to rotate the screw to the left when the shoulder 15 strikes the right-hand side of the stud 3. lt is of course obvious that the handle 6 will always gravitate into its lower IOO vertical position if turned only a half-turn from a vertical position but assuming that it be left in a horizontal position it would remain there but for the ability of the lug 51 to pass the present lower end of the stud 8, for, considering Fig. 1 2 in a horizontal position it is quite obvious that when the handle is released the preponderance of Weighton the left-hand end will cause the hub 10 to rotate to the left, carrying lug or shoulder l14 away from the right-hand end of stud 8 until dit arrives at a position perpendicular to the formed with a shoulder 18 and the outer side of the jaw 2 with a fulcrum-bearing 19, which is rounded and which bears against the shoulder 18 during the oscillatory movement of the jaw 2 and extension 17. As before intimated, this oscillatory movement when produced independently of the screw 3 is effected by means of a treadle accessible to the foot of the operator at a point on or near the floor, so that the jawsmay be manipulated or opened or closed, as desired, very rapidly without operating the screw 3, thus leaving both hands of the operator free for the Work to be done.

Instead of carrying the two extensions 16 17 entirely down to the floor and there connecting them together by suitable operating mechanism comprising a treadle this operating mechanism is located at a higher elevation than the floor, sovthat it wilI not be in the way of the feet of the operator or liable to become entangled with the operators clothing. Hence the mechanism which oscillates the extension or lever 17 with relation to the extension 16'is located considerably above the floor, as shown in Fig. 1, and is operatively connectedwith one or more oor-treadles 20 21, which in this exemplification of the invention are utilized, respectively, for operating the treadle-lever 22, whereby the jaws are forced together, and the treadle-locking dog 23, which holds said lever in position. These two treadles 20 21 are shown as two short sections of plank or other suitable members resting freely at their lower ends upon the floor and, if desired, held in place at their lower ends by screws 24 passing loosely therethrough, so that the position of the treadles may be readily shifted when desired and connected at their upper ends by any suitable connections 25 26, respectively, with the lever 22 and dog 23.

This form of treadle is preferable, for the reason'that ,aside from being cheap and simple will readily adapt itself to different positions of the vise, which is preferably swiveled to the bench 27 on a vertical axis, so that it may be used as either a left or a right hand vise or directly in front of the operator. In thus swiveling the vise the extension 16 is encompassed by a clamping collar 28, having flanges 29, whereby it may be secured to the bench 27, and a tightening device, whereby the floor, the lower end of the extension- 16 having a pivot 34, so that the vise may turn or swivel on the standard 33.

To one of the extensions 16 17 preferably the extension 17, is secured a connecting-bar 35, which is rendered adjustable with relation to the standard 17 by means of a series of holes 36, formed in the bar, and a pin 37, projecting through the extension 17 and one of said holes. In order that the pin 37 may be withdrawn readily and at `the same time the expanding action of a coil-spring utilized for holding it in place, it is provided with an elbow 38, as shown in Fig. 11, having a branch 39, passing back through the extension 17 at a point above the bar 35 and provided with a button 40,- between which and said extension is interposed coil-spring 41, which serves to hold the pin 37 in place, but which pin maybe withdrawn by pressure against the button 40', compressing the spring 41.

The end of the bar 35 opposite that in which the holes 36' are formed is connected with capability of limited movement with the extension 16, so that the extension 17 may move the requisite distance for forcing the jaws together, while preventing the lower end of the latter extension from becoming unduly displaced with relation to the extension 16. This connection is effected through the agency of a pin 42, passing through extension 16 and through slot 43 in bar 35, whose end passes loosely through the lower end of extension 16 between two inclines 44,

vformed on extension 16 and adapted to be engaged by two cams 45 46, respectively, which are pivotally secured to bar 35 by 'means of pivot 47 and are yoked together below the bar by a cross connection 48, to one end of which is lsecured or formed a lever 49, which when depressed acts to force the cams 46 against the inclines44, and thereby crowd the bar 35 outwardly away from ex- IOO IIC

tension 16 and pinch the jaws together. rI`his lever 49 is provided on one side with a lug or pin 50, which engages in a slot 51 in the treadle-lever 22, and the treadle-lever 22 is pivoted at 52 to the arms 53 of a toothed segment 54, and this in turn is rigidly secured to the side of extension 16 by bolts or screws 55 56 passing through the arms 53. The lever-locking dog 23 is pivoted to and carried by the treadle-lever 22 and engages the seg'- nient 54 for holding lever 22 against upward movement, lever 22 being forced downwardlj,T by treadle 2O in opposition to a spring or other yielding device 57, secured to lug 5S on lever 49 and to the extension 16, thus serving to restore the jaw-operating mech anisni to its normal elevated position. The bar 35 is pulled inwardly or restored to its normal position for throwing the jaws open by means of the spring 5S, secured at one end to the bar 35 and at the other end to extension 16.

`With the jaw-operating mechanism arranged in the described manner with relation to the downward extensions 16 17 it will be seen that the vise is being used directly in front of the operator. This mechanism will be entirely out of the way under the bench, and when the vise is turned to be utilized either as a right-liand or a left-hand vise such mechanism will be still out ofthe way and on one side of the operator and always on the side opposite that on which the vise is projected with relation to its vertical axis.

In the modification shown in Figs. 14 to 1S, inclusive, a lever 22L is pivoted at 52a to the side of the downward extension 16 and carries a spring-actuated locking dog or pawl 23a, arranged to engage the teeth of a segment-rack 54, which is secured in any suitable way to the extension 16, and to the coniiecting-bar 35 is secured one end of a link 22h, whose other end is pivoted to the lever 22a in any suitable way-such, for example, as shown in Fig'. IS-that is to say, by forming a round head 22C on the link and inserting the same in a circular socket 22d in the lever, the head 22O being held in place by a faceplate 22", so that when the lever 22EL is pushed downwardly it will exert great power against the bar 35 and will force the extension 17 outwardly, and when the lever 22at is elevated. dog 23a being released, the extension 17 will be drawn inwardly and the jaws 1 2 opened. The lever 22a may be raised to its elevated position when released by suitable spring 57, attached to the extension 16 and the link 22h. The operating mechanism thus constructed possesses great power, and it is simple and entails but the minimum amount of friction. In this form of the invention the clamp for holding the extension 16 is also somewhat modified. It is shown composed of two members 29a 29h, upon one of which is formed a lug 29C, having a passage through which passes a lug 29d, formed on the other one. The latter also has an additional lug 29e, similar to the lug 29d, which passes by the lug 29C on the outer side thereof, and between tlie two lugs 29d 29C is pivoted a cam 291', having a handle 29g, the cam being adapted to bear against the lug 2)c when it is rotated, and thereby pull the clamp members 2Sa toward each other.

In Fig. 17 is shown a slight modification in the pin-lock for the bar 35, which comprises a guide-pin 39a and a lockiiig-pin 37, secured to or formed on ahead 38a, and against this head bears a leaf-spring 41a.
